SEWAGE TREATMENT

Our solutions for the treatment of sewage provide the lowest whole of life cost available with > 50% lower energy than other technologies. They also provide the ability to manage peak flow conditions whilst still providing high quality effluent outcomes and the ability to integrate reuse application.

SLUDGE TREATMENT

We specialise in an alternative low energy, lower cost solution to managing sludge compared to traditional mechanical dewatering processes such as belt presses and centrifuges. We have partnered exclusively with world-leading engineering firm, Orbicon who are specialists in Sludge Treatment Reed Beds (STRBs). They have successfully been used in Europe for several decades treating sludge from sewage plants from 20,000 –250,000 EP and are delivering significantly lower whole-of-life costs to dewater, treat and reuse sludge.

LANDFILL LEACHATE TREATMENT

No landfill site is exactly the same which makes it difficult to apply an “off-the-shelf” solution to leachate treatment. Our team is able to draw on a wide range of proven technologies using a mix of traditional engineering and ecological processes to optimally match the treatment to the leachate composition whilst considering the ultimate sustainable disposal solution required.

INDUSTRIAL WASTEWATER TREATMENT

Every industrial wastewater has different characteristics – contaminant profile, volumes, operational variability, site constraints and disposal requirements. The most cost effective treatment solutions are those that are developed specifically for a particular industry’s situation rather than forcing an off the shelf treatment process to fit the wastewater framework.

MINING & RESOURCES WASTEWATER TREATMENT

Mining and resource companies face some of the toughest water challenges due to the scale of operation and typical remoteness of facilities. By improving the effectiveness of water management and reducing operation and maintenance costs of treatment can translate to millions of dollar savings over the life of a mining operation.

ECOLOGICAL SERVICES

Our team provides the skillset required to design, plant, and maintain ecological systems in a range of climates. With expertise in wetlands, ecology and horticulture, we are able to integrate and deliver a range of ecological solutions to meet varying project needs. Projects include stormwater systems, riparian and catchment reforestation, creation and provision biosequestration carbon offset.

Technologies

Trickling Filters

Plastic media has transformed the treatment capability of trickling filters making them two to three times more effective for a given volume over traditional stone fill. Reductions of more than 95 percent are now possible in BOD and ammonia, making trickling filters a viable option in many instances.

Sludge Treatment Reed Beds

Sludge treatment reed beds (STRBs) are an alternative low energy, lower cost solution to managing sludge compared to traditional mechanical dewatering processes such as belt presses and centrifuges. They comprise a series of gravel/sand basins that are planted with wetland plants/ reeds and are capable of treating many types of sludge including digested or undigested activated sludge, and water treatment works sludge.

Sub Surface Wetlands

Sub-Surface Flow Treatment Wetlands are ecological engineered systems comprising planted gravel/sand substrate where flows pass through the system below the ground. They rely on mechanisms such as physical filtration and biofilms, growing on gravel or other media, and plant roots. They can be divided it Horizontal Flow Sub-Surface wetlands or Vertical Flow Sub-Surface wetlands.

Surface Flow Wetlands

Surface Flow Treatment Wetlands are commonly used for treating wastewaters and stormwaters. They comprise a shallow containment dam arrangement with dense coverage of plants and the water flows through the stems of the plants about 200-300mm above the surface. The stems, leaf matter, and detritus provided by the wetland plants afford a rich organic surface for healthy microbiological populations to grow and treat water, as it passes through the vegetation and biomass.

Waste Stabilisation Ponds

Waste stabilisation ponds are commonly used for the treatment of sewage due to their operational simplicity and low mechanical requirements, including low power demand. This makes them an attractive solution for remote, regional and privately operated treatment facilities.

Effluent Disposal

Developing a comprehensive wastewater management strategy does not only entail selecting an appropriate treatment solution. It also involves finding suitable disposal pathways for the final effluent. In fact, treatment processes are too often decided upon without first fully understanding disposal pathway options, and determining the water quality specifications that are required from the treatment infrastructure.
